LED module for flashing lamp and flashing lamp

Abstract

The present invention provides an LED module that can prevent breakage of an LED chip due to pulse lighting for a flash when the LED module is used in a flashing lamp. An LED module ( 10 ) for flashing lamp includes: an LED substrate ( 13 ); plural LEDs ( 12 ); and plural resin layers ( 11 ). In the LED module ( 10 ), the LEDs ( 12 ) are mounted on a mounting surface of the LED substrate ( 13 ). Each resin layer ( 11 ) is stacked on a surface of each LED ( 12 ) opposite to the LED substrate ( 13 ). Adjacent resin layers ( 11 ) stacked on the LEDs ( 12 ) are separated from each other.

The invention claimed is: 
     
       1. An LED module for a flashing lamp comprising:
 an LED substrate; 
 plural LEDs; and 
 plural resin layers, wherein 
 the LEDs are mounted on a mounting surface of the LED substrate, 
 each resin layer is stacked on a surface of each LED opposite to the LED substrate, 
 adjacent resin layers stacked on the LEDs are separated from each other, 
 adjacent LEDs are separated from each other; and 
 the number of LEDs mounted on the mounting surface of the LED substrate is 4 to 25 per 120 mm  2 . 
 
     
     
       2. The LED module for flashing lamp according to  claim 1 , wherein a distance between the adjacent LEDs is 0.2 to 0.5 mm. 
     
     
       3. The module for flashing lamp according to  claim 1 , wherein the LED has a width of 1.8 to 5.3 mm. 
     
     
       4. The LED module for flashing lamp according to  claim 1 , wherein an effective luminous intensity is 6,000 to 20,000 cd per flashing time of 1 to 5 msec. 
     
     
       5. The LED module for flashing lamp according to  claim 1 , wherein a brightness is 300,000 to 1,600,000 lumen (lm). 
     
     
       6. The LED module for flashing lamp according to  claim 1 , wherein the resin layer is a phosphor resin layer. 
     
     
       7. A flashing lamp comprising:
 an LED module serving as a light source; 
 a light distribution unit; 
 a housing having an opening; and 
 a light transmissive cover, wherein 
 the LED module is the module for flashing lamp according to  claim 1 , 
 the LED module and the light distribution unit are disposed inside the housing, 
 the light distribution unit is disposed on a light emission side of the LED module, and 
 the light transmissive cover is disposed over the opening of the housing. 
 
     
     
       8. The flashing lamp according to  claim 7 , wherein the flashing lamp is for flashing for the landing guidance of an aircraft.
